Google's AI-powered design tool, Stitch, is set to receive a substantial wave of new capabilities that could reshape how designers and developers approach UI creation. Stitch was launched at Google I/O 2025 as a Google Labs experiment that turns text prompts and images into complete UI designs with frontend code, powered by Gemini models. Since then, it has grown rapidly, and the next batch of updates, found hidden in recent builds by TestingCatalog, suggests Google is pushing the tool well beyond its original scope.
BREAKING 🚨: Google is working on Live Voice Mode for Stitch! Users will be able to trigger design changes, discuss potential improvements, or have a live design critique.

The most notable upcoming addition is a voice mode, which would let users speak naturally to generate and iterate on UI screens in real time. This feels like a natural evolution of what some have started calling "vibe design", the visual counterpart to vibe coding, where casual, conversational input replaces manual pixel work. Alongside voice, a new design systems feature will allow users to import tokens directly from a URL, automatically pulling a site's design language into Stitch. This alone could save hours of manual setup for teams working with established brand guidelines.
On the prototyping front, Stitch is gaining more granular screen-by-screen controls. Users will be able to add missing screens, navigate through flows in a dedicated prototype window, and generate increasingly detailed prototypes. While some of this functionality technically exists today, it has been recently updated and expanded. A new "Studio" tab is also appearing in the navigation bar, opening a side panel where users can select from various generation modes, including:
- Web marketing kits
- UX critique summaries
- Accessibility audits
- Missing state generation (errors, loading screens)
- Developer handoff specs with full typography details
These go far beyond the current App Store asset generation that Stitch already supports.
What makes this collection of features notable is the breadth of who it serves. Designers get voice-driven prototyping and design system imports. Developers get structured handoff specs. Marketing teams get the ability to generate promotional materials directly from finished UI screens. Google has positioned Stitch as a bridge between design and development, and the tool was born from a collaboration between a designer and an engineer looking to optimize both workflows. These upcoming additions extend that bridge to cover UX review, accessibility, and go-to-market, making Stitch a more complete end-to-end product design tool. No release timeline has been confirmed.
